CURTAIN-RING.

SPECIFICATION forming part of Letters Patent N 0. 646,366, dated March27, 1900.

Application filed August 30, 1899- Serial No. 728,954. (No model.)

To all whom zit may concern.-

Be it known that I, WILLIAM F. DURST, a citizen of the United States ofAmerica, residing at 845 WVilloughby avenue, in the city of New York,borough of Brooklyn, county of Kings, State of New York, have inventedcertain new and useful Improvements in Ourtain-Rings, of which thefollowing is a specification.

My invention relates to curtaimrings having antifriction-rollers and theobject of said invention is to provide a simple, strong, and efficientcurtainring of the character described which can be readily and cheaplyconstructed.

In the accompanying drawings, Figure 1 illustrates a side view of theseparate parts which comprise a curtain-ring embodying my inventionbefore said parts are assembled.

Fig. 2 is a side view, partly in section, of a completed curtain-ringembodying my invention. Fig. 3 is an enlarged detail fragmentarysectional view of a portion of the same, the view being taken on theline 3 3 of Fig. 4. Fig. 4 is a transverse sectional view of the same,taken on the line 4B 4 of Fig. 3.

In order that a better understanding of my construction may be arrivedat, I will first describe the manner in which the ring is constructed.

A suitable split curtain-ring proper, A, is provided, and upon this ringis placed a pl urality of endless roller-bearing sleeves B, the internaldiameter of which is substantially that of the thickness of the curtain-ring proper. Each of these endless roller-bearing sleeves is providedwith a flange a. After the roller-bearing sleeves have been placed uponthe ring the endless rollers O are placed thereon, and after theyarebrought into place upon their sleeves the straight edge of eachsleeve is turned up, as indicated at b in Fig. 2 of the drawings, sothat the roller of each sleeve is retained thereon against lateralmovement, but is permitted to rotate upon the sleeve, as will beunderstood. The sleeves are then moved to the proper position upon thering, as indicated in Fig. 2 of the drawings, and are secured in placeby means of solder or otherwise, as indicated at 0. One of the sleevesshould be placed over the split portion of the ring, so as to cover thejoint, as indicated in Figs. 2 and 3 of the drawings, and to present anapparently-endless ring. When the parts have been secured in thismanner, the ring is ready for use and the rollers 0 will be adapted tobear upon the curtain-pole with which they cooperate, as indicated indotted lines in Fig. 2 of the draw- 1ngs.

It will be observed that by my invention I am enabled to make theroller-bearing sleeves and the rollers endless and to provide a strongand efficient curtain-ring the parts of which can be rapidly assembledand which can be made at little cost.

While I have referred throughout to the use of a plurality of rollers oneach ring, it may be found desirable to employ only a single roller oneach ring.

Having described my invention, what I desire to secure by Letters Patentis- 1. A curtain-ring comprising a split ring proper, endless shoulderedroller-bearing sleeves secured on the said ring and through which thering passes, and a roller secured against lateral movement between theshoulders on each of said sleeves.

2. A curtain-ring comprising a split ring proper, endless shoulderedroller bearing sleeves secured on said ring and through which the ringpasses, one of said sleeves being secured over the joint of the ring andan endless roller secured against lateral movement between the shoulderson each of said sleeves.

3. A curtain-ring comprising a split ring proper, endless roller-bearingsleeves each with an internal diameter corresponding substantially tothe thickness of the ring and having upturned shoulders on each side ofsaid sleeve and through which sleeves the ring passes, one of saidsleeves being secured on said ring and over the joint thereof and anendless rollersecured against lateral movement between the shoulders oneach of said sleeves.
